Performs silicon late policy update.

The meaning of Policy is defined by silicon code.

It could be the raw data, a handle, a Protocol, etc.

The input Policy must be returned by SiliconPolicyDoneLate().

In FSP or non-FSP path, the board may use additional way to get
|
the silicon policy data field based upon the input Policy.

@param[in, out] Policy Pointer to policy.
